Do druku 3D, frezowania CNC czy ręcznego montażu skomplikowanych konstrukcji potrzebna jest formalna specyfikacja przedmiotu obrabianego, czyli jego części i sposobu ich połączenia. Proces osiągnięcia tego celu nazywa się projektowaniem wspomaganym komputerowo (CAD). Proces przekształcania modelu CAD w serię instrukcji, które można wykonać na maszynie, nazywa się wytwarzaniem wspomaganym komputerowo (CAM). FreeCAD może wykonywać obydwa procesy, chociaż ten pierwszy nieco lepiej od drugiego.

FreeCAD jest otwartoźródłowym programem CAx i RAD opartym na OpenCasCade, QT i Pythonie. Cechuje go kilka kluczowych rozwiązań, takich jak: zapisywanie makr, automatyczne tworzenie stanowiska pracy, zdolność do pracy w charakterze serwera, dynamiczne ładowanie rozszerzeń aplikacji i niezależność od platformy.

Obecnie FreeCAD może importować i wyświetlać modele CAD w formatach IGES, STEP i BREP a obiekty MESH w STL, BMS, AST i Wavefront OBJ. Funkcje edycji i modelowania są obecnie dość ograniczone.

To jest metapakiet dla pakietów komponentów FreeCAD.
